The main remedial actions to prevent voltage instability problems are load shedding and rescheduling of generating units. In AC/DC networks, the presence of high voltage direct current (HVDC) links equipped with voltage source converter (VSC) provides an efficient active and reactive power support. As the voltage stability is a local phenomenon, the rescheduling of an HVDC link could change the arrangement of critical buses and the stability margin of the entire power system as a remedial action. Considering this problem, a new optimization algorithm is proposed to provide the desired voltage stability margin in interconnected AC/DC networks taking into account the post contingency conditions and minimizing the cost of remedial actions. The regulation of the converter operating point is presented as a novel remedial action. The well-known loading margin (LM) index is used as the voltage stability criterion and different VSC-HVDC structures, i.e. singleinfeed, multi-infeed and multi-terminal HVDC systems are considered. The effectiveness of the proposed algorithm is evaluated using an AC/DC system comprising the IEEE 118bus and New England 39-bus test systems. The results show that the proposed algorithm could provide the desired value of LM with the minimum value of load shedding and the control cost.

“…The rescheduling of the generators is one of the primitive measures adopted to control congestion. Fang et al designed a optimal rective power dispatched problem considering the rescheduling of the generators [13]. Othman et al sorted the critical generator to schedule their power delivery to maintain the available transfer capability [14].…”

The issue to alleviate congestion in the power system framework has emerged as an alluring field for the power system researchers. The research conducted in this article proposes a cuckoo search algorithm based congestion alleviation strategy with the incorporation of wind farm. The bus sensitivity factor data are computed and utilized to sort out the sutiable position for the installation of the wind farm. The generators contributing in the real power rescheduleing process are selected as per the generator sensitivity values. The cuckoo search algorithm is implemented to minimize the congestion cost with the embodiment of the wind farm.The proposed method is tested on 39 bus New England framework and the results obtained with the cuckoo search based congestion management approach outperforms the results opted with other heuristic optimization techniques in the past research literatures.

“…Global optimisation methods increase the possibility of obtaining global optimal solution, and can be divided into two kinds: deterministic algorithms, e.g. the filled function method [25], the interval optimisation algorithm [26] etc., and stochastic algorithms, e.g. the genetic algorithm [27], the monkey king evolution (MKE) algorithm [28], the fruit flies algorithm [29], the cat swarm optimisation algorithm [30], the bird swarm algorithm [31], the ant colony algorithm [32], the fish swarm algorithm [33] etc.…”
